Shortly, nearest future, soon - do you really believe that Bitcoin price can grow all the time? Grow so quickly, to update ATH all the time. I think we start to forget how low Bitcoin price can drop, and how much time it will take to recover. Dont forget about 4 year price cycle. Dont forget how the price grew thanks to ICO and Elon Musk, and NFT probably. I think that the price will be updated only when a new "pusher" will appear on the market. A new hype that will attract newmoney to cryptocurrency, that will wake up peoples interest into spending and investing.
That 4 year cycle is an old talk and wasn't correct this year. We had a big increase to ATH during April, and then we had a 50%+ crash and then we recovered to a new ATH once again in the same year. This all happened within one year, which means that people are definitely looking into something for themselves as well, it is going to be not so weird to expect it to be 100k somewhere in 2022 as well, which could mean the start could happen during December too.
It is why I believe that bitcoin could always fall like you said, but that doesn't need to happen all the time, it could happen at different periods as well and maybe this isn't one of those times, it was a correction and we will recover and break ATH again, or maybe we won't but there is no guarantee which one of those things will happen. This is why people believe "anything could happen" is more likely than saying this or that will happen.
